111 GCC Requirement

For Linux host systems the Intel FPGA Emulation Platform for OpenCL softwarerequires that you have at least GCC 720 on your system GCC 720 provides thelibstdc++so6 shared library Newer versions may work as well Specificallylibstdc++so6024 library or later is required that defines GLIBCXX_3424and CXXABI_1311 symbol versions

If you do not have a sufficiently new GCC and libstdc++so6 library installed youmay encounter issues when trying to run OpenCL host programs that target the IntelFPGA Emulation Platform for OpenCL software If the correct version of libstdc++so library is not found at run time the call to clGetPlatformIDs function fails toload the emulation platform and returns CL_PLATFORM_NOT_FOUND_KHR (error code-1001) Depending on the version of libstdc++so library found the call toclGetPlatformIDs function may succeed but a later call to the clCreateContextfunction might fail with CL_DEVICE_NOT_AVAILABLE (error code -2)

To verify the GCC version you are using run the following command

$ gcc -dumpversion

Ensure that the command reports version 720 or greater If you do not have asufficiently recent GCC use the following instructions to install a newer GCC on yoursystem

Installing GCC 7

The process for installing the required GCC differs depending on the host operatingsystem as described in the following sections

Ubuntu

If your Ubuntu version does not include GCC 7x or later by default you can obtainGCC 7x by using the following commands

$ sudo add-apt-repository ppaubuntu-toolchain-rtest $ sudo apt-get update $ sudo apt-get install gcc-7 g++-7$ sudo update-alternatives --install usrbingcc gcc usrbingcc-7 60 --slave usrbing++ g++ usrbing++-7 $ sudo update-alternatives --config gcc

Note Ensure that you select gcc-7 for the sudo update-alternatives command Theupdate-alternatives utility can be used to swap between GCC versions asrequired

CentOS and Red Hat Enterprise Linux Version 7

Note Unfortunately installing the Developer Toolset (for example devtoolset-7) does notprovide the desired result because it does not include a newer libstdc++so6library The Developer Toolset provides a custom version of the GCC that uses theolder libstdc++so6 library originally installed on the system

UG-OCL001 | 20210621

For CentOS and Red Hat Enterprise Linux version 7 Intel recommends that youcompile GCC from source and install it using the following instructions

1 Download the tarball of the GCC version you want to install

wget httpwwwnetgullcomgccreleasesgcc-720gcc-720targz

2 Unpack the tar archive and change the current working directory

tar zxf gcc-720targzcd gcc-720

3 Install the bzip2 package

yum -y install bzip2

4 Run the download_prerequisites script to download some prerequisitesrequired by the GCC

Note You must run the script from the top-level of the GCC source tree

contribdownload_prerequisites

5 Once the prerequisites are downloaded execute the following command to startconfiguring the GCC build environment

configure --disable-multilib --enable-languages=cc++

6 Run the following command to compile the source code Compilation may take afew hours to complete

make -j 4make install

7 Refer to Verifying Your GCC Installation on page 8 section for instructions toverify if your GCC installation was successful

SUSE Enterprise Linux 12

For SUSE Intel recommends that you compile GCC from source and install it byfollowing the instructions provided for CentOS and Red Hat Enterprise Linux

Verifying Your GCC Installation

To verify your GCC installation ensure the following

bull Shell can find the correct GCC binaries

bull The newer GCC is using correct shared libraries (in particular libstdc++so6)

This depends on how you installed the GCC and set the $PATH and$LD_LIBRARY_PATH environment variables You might have installed the GCCbinaries and libraries to the default locations for your operating system

Verifying the Correct GCC Binaries are Used

Perform these steps

1 Verify if your newly-installed GCC binaries are being used

$ which gcc

UG-OCL001 | 20210621

2 Ensure the output points to the correct GCC

$ gcc ndashdumpversion

3 Ensure GCC reports a version of 720 or higher

If the above commands do not report the correct GCC version modify your $PATHenvironment variable to point to the location of the newly installed GCC binaries

For Ubuntu the default install location for GCC binaries is usrbin and librariesis usrlib64 However binaries are versioned (for example gcc-7) Use theupdate-alternatives utility to ensure gcc is a symbolic link to the desired GCCversion On Ubuntu systems the $PATH and $LD_LIBRARY_PATH environmentvariables need not be updated because the shell and dynamic linker shouldautomatically search in the correct places for the binaries and libraries respectively

Tip You can place the following command in your shell startup script or an environmentsetup script so that the development environment is automatically set up when youenter it

$ export PATH=ltpathtonewgccgtbin$PATH

To verify that your $PATH environment variable has been modified appropriately usethe following command

$ echo $PATH

Check the output to ensure that the path to your newly installed GCC is part of your$PATH Repeat these steps to ensure the correct GCC binaries are being used

Verifying the Use of Correct Shared Libraries

To verify that the new GCC libraries are being used check that a test compile linksagainst the correct libstdc++so6 library version by using the following steps

$ echo int main() return 0 gt testcpp $ g++ -Wl--no-as-needed testcpp -o test $ ldd test linux-vdsoso1 =gt (0x00007fff6df35000) libstdc++so6 =gt usrlib64libstdc++so6 (0x0000003451600000) libmso6 =gt lib64libmso6 (0x0000003446a00000) libgcc_sso1 =gt lib64libgcc_sso1 (0x000000344d600000) libcso6 =gt lib64libcso6 (0x0000003446600000) lib64ld-linux-x86-64so2 (0x000055ff56398000) $ strings usrlib64libstdc++so6 | grep GLIBCXX_3424 GLIBCXX_3424

Use the output from the ldd command to determine the path to the libstdc++so6 library that you need to use with the strings command (see highlightedstrings your output may be different) Ensure that the strings command returnsGLIBCXX_3424

UG-OCL001 | 20210621

Alternatively the libstdc++so6 file is often a symbolic link to the actual librarywhich has the version number appended Therefore instead of calling the stringscommand on libstdc++so6 library you can use the following readlinkcommand to verify libstdc++so6 points to a sufficiently new version of libstdc++

$ readlink usrlib64libstdc++so6 libstdc++so6024

Use the output from the ldd command (executed earlier) to determine the path tolibstdc++so6 that you need to use with the readlink command Ensure thatreadlink command reports that your libstdc++so6 is a symbolic link tolibstdc++so6024 Versions newer than 6024 may also work

If the above commands do not report the correct shared libraries are being used youmight need to modify your $LD_LIBRARY_PATH environment variable to point to thelocation of the newly installed GCC libraries

$ export LD_LIBRARY_PATH=ltpathtonewgccgtlib64$LD_LIBRARY_PATH

To verify that your $LD_LIBRARY_PATH environment variable has been modifiedappropriately run the following command

$ echo $LD_LIBRARY_PATH

Check the output to ensure the path to your newly installed GCC libraries are includedin $LD_LIBRARY_PATH Repeat the above steps to ensure the correct GCC libraries(in particular libstdc++so6) are being used

12 Intel FPGA SDK for OpenCL Pro Edition and OpenCL BSPBackwards Compatibility

The Intel FPGA SDK for OpenCL Pro Edition Version 212 compiler is compatible withOpenCL board support package (BSP) Version 202 and Intel Acceleration StackVersion 201 and Version 121 This backwards compatibility allows you to use olderOpenCL BSPs with newer compilers However some newer OpenCL compiler featuresmight not be available to use with older OpenCL BSPs

Note Starting from the 203 release support for Windows and Linux OpenCL BSPs isremoved Use version 202 or older OpenCL BSPs available at Download Center forFPGAs as a reference If you want to migrate your OpenCL BSP to a newer versionfollow the recommended steps provided in the Reference Platform Porting Guidesavailable under Intel FPGA SDK for OpenCL documentation

To use an older OpenCL BSP with the Intel FPGA SDK for OpenCL you must have aversion of Intel Quartus Prime Pro Edition with the same version number as yourOpenCL BSP For example to use a Version 202 BSP with Intel FPGA SDK for OpenCLPro Edition Version 212 you need Intel Quartus Prime Pro Edition Version 202

25 Installing an FPGA Board

Before creating an OpenCL application for an FPGA accelerator board or SoC deviceyou must first download and install the Intel Reference Platform or the CustomPlatform from your board vendor Most Custom Platform installers requireadministrator privileges

To install your board into a Windows host system invoke the aocl installltpath_to_customplatformgt utility command

The steps below outline the board installation procedure Some Custom Platformsrequire additional installation tasks Consult your board vendors documentation forfurther information on board installation

1 Follow your board vendors instructions to connect the FPGA board to your system

2 Download the Custom Platform for your FPGA board from your board vendorswebsite

Note Starting from 203 release support for Windows OpenCL BSPs is removedUse 202 or older OpenCL BSPs available at Download Center for FPGAs as areference If you want to migrate your OpenCL BSP to a newer versionfollow the recommended steps provided in the Reference Platform PortingGuides available under Intel FPGA SDK for OpenCL documentation

3 Install the Custom Platform in a folder that you own (that is not a system folder)

You can install multiple Custom Platforms simultaneously on the same systemusing the SDK utilities such as aocl diagnose with multiple Custom PlatformsThe Custom Platform subdirectory contains the board_envxml file

In a system with multiple Custom Platforms ensure that the host program usesthe FPGA Client Driver (FCD) to discover the boards rather than linking to theCustom Platforms memory-mapped device (MMD) libraries directly If FCD iscorrectly set up for Custom Platform FCD finds all the installed boards at runtime

4 Set the QUARTUS_ROOTDIR_OVERRIDE user environment variable to point to theIntel Quartus Prime Pro Edition software installation directory

5 Add the paths to the Custom Platform libraries (for example path to the MMDlibrary of the board support package resembles ltpath_to_customplatformgtwindows64bin) to the PATH environment variable setting

For information on setting user environment variables and running theinit_opencl script refer to the Setting the Intel FPGA SDK for OpenCL ProEdition User Environment Variables section

6 Invoke the command aocl install ltpath_to_customplatformgt at acommand prompt

Invoking aocl install ltpath_to_customplatformgt installs both the FCDand a board driver that allows communication between host applications andhardware kernel programs

251 Enabling Backwards Compatibility for an FPGA Board

To enable a board with a downlevel OpenCL BSP you need a version of Intel QuartusPrime Pro Edition with the same version number as the OpenCL BSP version

For example you can use Version 202 OpenCL BSP with Intel FPGA SDK for OpenCLVersion 212 and Intel Acceleration Stack Version 201 and Version 121

UG-OCL001 | 20210621

After you have installed and configured the required version or versions of IntelQuartus Prime Pro Edition you enable your backwards compatible boards by settingthe QUARTUS_ROOTDIR_OVERRIDE environment variable and running the aoclinstall command so that your Intel Quartus Prime Pro Edition version matches yourOpenCL BSP version number

Before you set the QUARTUS_ROOTDIR_OVERRIDE environment variable and run theaocl install command install and configure the version of Intel Quartus Prime ProEdition that your OpenCL BSP needs

Also install your FPGA board or boards following the instructions in Installing an FPGABoard on page 19

To enable a board with a backwards compatible OpenCL BSP

1 Set the QUARTUS_ROOTDIR_OVERRIDE to point to the version of Intel QuartusPrime Pro Edition that your OpenCL BSP needs

For example if you have Version 202 OpenCL BSPQUARTUS_ROOTDIR_OVERRIDE must point at Intel Quartus Prime Pro EditionVersion 202

set QUARTUS_ROOTDIR_OVERRIDE=ltpath_to_quartus_installgtquartus

2 Run the aocl install ltpath_to_customplatformgt command with the pathto your backward compatible OpenCL BSP as the value forltpath_to_customplatformgt

For example to point to a Version 202 OpenCL BSP for the Intel Arria 10 GXFPGA Development Kit Reference Platform install the board with the followingcommand

aocl install ltYOUR_PATH_TO_V202_OpenCL_BSPgta10_ref

After you complete these steps Intel SDK for OpenCL commands like aocldiagnose should work correctly with your backlevel OpenCL BSP

The following instructions are for accessing the Hello World design

1 Access the hello_world folder

2 Copy it to a folder that you have write access for

Important Ensure that the folder name does not contain spaces

262 Compiling a Kernel for Emulation

To compile an OpenCL kernel for emulation include the -march=emulator option inyour aoc command

bull To compile the kernel for your target FPGA board at a command prompt navigateto the hello_world design and then invoke the following command

The Intel FPGA SDK for OpenCL Offline Compiler compiles the hello_worldclkernel source file and creates the hello_worldaocx emulation-specificexecutable file in the bin subdirectory

263 Building the Host Application

The ltlocal_path_to exm_opencl_hello_worldgthello_worldhello_worldsln file contains the host solution After you open this sln file inMicrosoft Visual Studio you can build the OpenCL host application in the maincppfile

If you are using Microsoft Visual Studio you need the FCD and the Installable ClientDriver (ICD) from Khronos The ICD driver links the host against the OpenCLdllwhich requires the FPGA Client Driver (FCD) installed For installing FCD refer to Installing an FPGA Board on page 19

To set up Microsoft Visual Studio with FCD and ICD perform the following tasks priorto building the host application

1 Verify that FCD and ICD are set up correctly using the aocl diagnose -icd-only command If both FCD and ICD are installed correctly you should see thefollowing output

264 Emulating Your OpenCL Kernel

To emulate your OpenCL kernel run the emulation aocx file on the platform onwhich you build your kernel

To emulate your kernel perform the following steps

1 To run the host application for emulation first define the number of emulateddevices by invoking the setCL_CONFIG_CPU_EMULATE_DEVICES=ltnumber_of_devicesgt command andthen run the host applicationThis command specifies the number of identical emulation devices that theEmulator needs to provide By default the emulator platform provides a singleemulator device Therefore if your host code requires only a single device you donot need to set the CL_CONFIG_CPU_EMULATE_DEVICES environment variableThe host application for the hello_world design example only requires a singledevice so you may skip setting this environment variable

Remember When the host is compiled and running for the emulator platformonly the emulated devices are available that is access to all physicalboards is disabled

2 After you run the host application unset theCL_CONFIG_CPU_EMULATE_DEVICES variable by invoking the setCL_CONFIG_CPU_EMULATE_DEVICES= command

Upon successful emulation of your kernel you should see the following output

28 Updating the Hardware Image on the FPGA

If applicable before you execute an OpenCL kernel program on the FPGA ensure thatthe flash memory of the FPGA contains a hardware image created using a currentversion of the OpenCL software

Remember If your Custom Platform requires that you preload a valid OpenCL image into the flashmemory for every major release of the Intel Quartus Prime Design Suite program theflash memory of the FPGA with a hardware image compatible with the current versionof the software

282 Programming the Flash Memory of an FPGA

Configure the FPGA by loading the hardware image of an Intel FPGA SDK for OpenCLdesign example into the flash memory of the device When there is no power theFPGA retains the hardware configuration file in the flash memory When you power upthe system it configures the FPGA circuitry based on this hardware image in the flashmemory Therefore it is imperative that an OpenCL-compatible hardware configurationfile is loaded into the flash memory of your FPGA

Preloading an OpenCL image into the flash memory is necessary for the properfunctioning of many Custom Platforms For example most PCIe-based boards requirea valid OpenCL image in flash memory so that hardware on the board can use theimage to configure the FPGA device when the host system powers up for the firsttime If the FPGA is not configured with a valid OpenCL image the system fails toenumerate the PCIe endpoint or the driver does not function

Before running any designs ensure that the flash memory of your board has a validOpenCL image that is compatible with the current OpenCL software version Consultyour board vendors documentation for board-specific requirements

Caution When you load the hardware configuration file into the flash memory of the FPGAmaintain system power for the entire loading process which might take a fewminutes Also do not launch any host code that calls OpenCL kernels or mightotherwise communicate with the FPGA board

To load your hardware configuration file into the flash memory of your FPGA boardperform the following tasks

1 Install any drivers or utilities that your Custom Platform requires

For example some Custom Platforms require you to install the Intel FPGADownload Cable driver to load your hardware configuration file into the flashmemory For installation instructions refer to the Intel FPGA Download Cable IIUser Guide

2 To load the hardware configuration file into the flash memory invoke the aoclflash ltdevice_namegt ltdesign_example_filenamegtaocx commandwhere ltdevice_namegt refers to the acl number (eg acl0 to acl127) thatcorresponds to your FPGA device and ltdesign_example_filenamegtaocx isthe hardware configuration file you create from theltdesign_example_filenamegtcl file in the design example package

For more information about compiling an aocx file refer to Creating the FPGAHardware Configuration File of an OpenCL kernel in the Intel FPGA SDK forOpenCL Getting Started Guide

3 Power down your device or computer and then power it up again

Power cycling ensures that the FPGA configuration device retrieves the hardwareconfiguration file from the flash memory and configures it into the FPGA

UG-OCL001 | 20210621

Warning Some Custom Platforms require you to power cycle the entire hostsystem after programming the flash memory For example PCIe-basedCustom Platforms might require a host system restart to re-enumeratethe PCIe endpoint Intel recommends that you power cycle thecomplete host system after programming the flash memory

UG-OCL001 | 20210621

Important Before you proceed review Emulating and Debugging Your OpenCL Kernel topic of theIntel FPGA SDK OpenCL Pro Edition Programming Guide

1 Verify that the LD_LIBRARY_PATH environment variable setting includes the pathsidentified in Setting the Intel FPGA SDK for OpenCL User Environment VariablesOpen a shell and then type echo $LD_LIBRARY_PATH at the command prompt

If the returned path do not include $INTELFPGAOCLSDKROOThostlinux64lib add it to the LD_LIBRARY_PATH setting

The $INTELFPGAOCLSDKROOTexamples_aoc contains sample applications ofvarying complexities that you can copy to your local and run on your FPGA

1 Access the hello_world directory

2 Copy it to a directory to which you have write access

Important Ensure that the directory path does not contain spaces

The compiles the hello_worldcl kernel source file and creates thehello_worldaocx emulation-specific executable file in the bin subdirectory

Build the host executable with the ltlocal_path_to_exm_opencl_hello_worldgthello_worldMakefile file

To build the host application perform the following tasks

1 If you did not run the aocl install command when performing the steps from Installing an FPGA Board on page 35 you must execute the following command

aocl install -fcd-only ltboard_package_pathgta10_ref

UG-OCL001 | 20210621

The ICD driver links the host against the libOpenCLso which requires the FPGAClient Driver (FCD) installed For installing FCD refer to Installing an FPGA Boardon page 35

Note If you do not have the root privilege refer to Installing an FPGA Board onpage 35

2 Navigate to the hello_world directory

3 Invoke the make commandThe hello_world executable is generated in the bin sub-directory

4 If you performed the step 1 then you must execute the following command

aocl uninstall -fcd-only ltboard_package_pathgta10_ref

To emulate your OpenCL kernel run the emulation aocx file on the platform onwhich you built your kernel The OpenCL Emulator uses a different OpenCL platformthan when targeting FPGA hardware

1 To run the host application for emulation invoke the envCL_CONFIG_CPU_EMULATE_DEVICES=ltnumber_of_devicesgtlthost_application_filenamegt commandThis command specifies the number of identical emulation devices that theEmulator needs to provide By default the emulator platform provides a singleemulator device Therefore if your host code requires only a single device you donot need to set the CL_CONFIG_CPU_EMULATE_DEVICES environment variable

For the hello_world design example run binhost -emulator The -emulator argument informs the host program to select the Intel FPGA EmulationPlatform for OpenCL

Upon successful emulation of your kernel you see the following output

UG-OCL001 | 20210621

Note bull The emulator in Pro Edition is built with GCC 720 as part of the offline compilerWhen executing the host program for an emulated OpenCL device the version oflibstdc++so must be at least that of GCC 720 In other words theLD_LIBRARY_PATH environment variable must ensure that the correct version oflibstdc++so is found

If the correct version of libstdc++so is not found the call toclGetPlatformIDs function fails to load the FPGA emulator platform and returnsCL_PLATFORM_NOT_FOUND_KHR (error code -1001) Depending on whichversion of libstdc++so is found the call to clGetPlatformIDs may succeedbut a later call to the clCreateContext function may fail withCL_DEVICE_NOT_AVAILABLE (error code -2)

If LD_LIBRARY_PATH does not point to a sufficiently new libstdc++so usethe following syntax to invoke the host program

env LD_LIBRARY_PATH=ltpath to sufficiently new libstdc++sogt$LD_LIBRARY_PATH lthostgt [host arguments]

bull To enable debugging of kernel code optimizations are disabled by default for theFPGA emulator This can lead to sub-optimal execution speed when emulatingkernel code

You can pass the -g0 flag to the aoc compile command to disable debugging andenable optimizations This enables faster emulator execution
